Based on: ... processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel(R) Xeon(R) CPU E31265L @ 2.40GHz stepping : 7 ... and grub2 (Not sure for ucode=scan): 1) intel-microcode2ucode microcode.dat 2a) cp intel-ucode/06-2a-07 /boot/microcode.bin or 2b) cat intel-ucode/* >/boot/microcode.bin 3) Make sure "ucode=-1" is in GRUB_CMDLINE_XEN 4) /sbin/grub2-mkconfig -o /boot/grub2/grub.cfg And you see microcode loaded on the serial console. -Don Slutz > Jan > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxx > http://lists.xen.org/xen-devel > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
